That only means a "nice to have", not "must have", feature. Sure it's convenient, but how often do you really need both and can't simply build twice? My Windows build is slow enough as is[*], I'd probably welcome the separation.
Note: with qmake's NMake generator, you *can* type "make debug" and it'll only compile the debug sub-targets. That doesn't work with the Unix Makefile one, so it won't work for macOS.

As a big CMake fan, I would love to see the whole QMake -> CMake conversion go forward.
To this point, and this point only, the following is what my company uses to build debug and release on windows
cmake --build . --config Debug --config RelWithDebInfo --target ALL_BUILD
For linux, we don’t have a method...
